Grundfos - UPS3 15-50/65 Domestic Heating Circulator - 130mm - 240V - Cast IronUPS3 15-50/65 130
High-efficiency canned-rotor circulator designed for circulating liquids in domestic heating systems. appropriate as stand-alone or integrated circulator pump in existing systems, as replacement or in new heating systems.
The pump features three control modes:
- constant-curve mode with three settings
- proportional-pressure control with two settings
- constant-pressure control with two settings
Furthermore, the speed can be controlled by a low-voltage PWM (Pulse Width Modulation) profile A – Heating.
Additionally, the straightforward and user-friendly one-button interface makes replacement and settings uncomplicated and fast.
LEDs indicate the actual operating status as well as warnings and alarms
The design of the pump and chosen materials contribute to a long service life. The pump is self-venting through the system, which contributes to straightforward commissioning. The space-efficient design, featuring a pump head with an integrated control box, fits into most common installations as well as boilers due to the ambient temperature range. Pump and motor form an integral unit without a shaft seal. The bearings are lubricated by the pumped liquid. These design features ensure maintenance-free operation. Servicing screw accessible from the front allows for straightforward access to the pump shaft if deblocking of the pump is required once it has been installed.
The pump housing is made of Cast Iron. The pump housing is electrocoated to improve corrosion resistance.
The motor is a synchronous permanent-magnet motor characterised by high efficiency. Pump speed is controlled by an integrated frequency converter incorporated in the control box.
The benchmark for the most high-efficiency circulators is EEI ≤ 0.20.
Suitable for: Commercial heating, District heating, Domestic heating

Grundfos - Magna3 25-40 Circulator Pump - 230V - Single Phase - Cast IronMAGNA3 25-40
The Grundfos MAGNA3 circulator pump is the well-suited choice for almost any building project – old or new. With its unrivalled energy efficiency, all-encompassing range and built-in communication capabilities, MAGNA3 is well-suited for engineers and specifiers looking to create high-performance heating and cooling systems. The pump is maintenance-free due to the canned-rotor type design. This also means that pump and motor form an integral unit without shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid. MAGNA3 features an intuitive display and allows you to connect wirelessly with the Grundfos GO Remote app, giving you access to enhanced reporting and monitoring. MAGNA3 model E has Bluetooth, which allows you to connect directly to the Grundfos GO app on your smart phone without any need for a dongle. The pump includes fieldbus communication via CIM modules as well as analogue and digital inputs and configurable relays. Control features include AUTOADAPT and FLOWADAPT. FLOWADAPT reduces the need for throttling valves, thus cutting costs on system components. MAGNA3 is the superior choice for a wide range of heating and cooling applications, including:
MAGNA3 is a single-phase pump characterised by the controller and control display being integrated in the control box. The pump also has a built-in differential pressure and temperature sensor. The pump housing is available in both cast-iron and stainless-steel versions. The composite rotor can is carbon-fibre reinforced, the bearing plate and rotor cladding are made of Stainless Steel and the stator housing is made of aluminium. The power electronics are air-cooled. MAGNA3 incorporates a 4-pole synchronous, permanent-magnet motor (PM motor). This motor type is characterised by higher efficiency than a conventional asynchronous squirrel-cage motor. The pump speed is controlled by an integrated frequency converter.- small chiller applications

Grundfos - Magna3 D 32-100F Variable Twin Speed Circulator - 240V - Cast IronMAGNA3 D 32-100 F
The Grundfos MAGNA3 D circulator pump is the well-suited choice for almost any building project – old or new. With its unrivalled energy efficiency, all-encompassing range and built-in communication capabilities, MAGNA3 D is well-suited for engineers and specifiers looking to create high-performance heating and cooling systems. The pump is maintenance-free due to the canned-rotor type design. This also means that pump and motor form an integral unit without shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid. MAGNA3 D offers three multipump modes: Alternating, backup and cascade operation.
In alternating and backup operation, only one pump operates at a time to ensure constant comfort. In alternating operation, the change from one pump to the other depends on time or energy. If a pump fails, the other pump will take over automatically. In backup operation, the backup pump is operated at intervals to prevent seizing. If the duty pump stops due to a fault, the backup pump will start automatically. In cascade operation, the pumps automatically switch on and off, adapting to the current consumption in the system. The two pumps communicate wirelessly. MAGNA3 D features an intuitive display and allows you to connect wirelessly with the Grundfos GO Remote app, giving you access to enhanced reporting and monitoring. MAGNA3 model E has Bluetooth, which allows you to connect directly to the Grundfos GO app on your smart phone without any need for a dongle.

Grundfos - JP 4-54 Booster Pump - Female Ported - 240V - Stainless SteelJP 4-54
Grundfos JP 4-54 is a self-priming single-stage centrifugal jet pump with axial inlet and radial outlet for straightforward adaption to local pipe system. With its excellent suction capacity, the JP pump is well-suited for transferring water from wells or ground tanks in a large variety of installations.
The JP pump is designed for smooth, long-term operation. The overall design is heavy-duty with excellent corrosion resistance thanks to the stainless-steel pump housing, composite impeller and paint application by electrophoresis. JP is small and space-efficient with a lifting handle that makes the pump handy and straightforward to carry. The space-efficient pump features a built-in ejector with guide vanes. This ensures optimum self-priming properties, featuring a suction lift of up to 8 metres. The self-priming pump also ensures stable operation as it is able to lift liquid from below the inlet level and can handle a mix of air and liquid until the pump reaches fully-primed pumping condition.
The JP pump has built-in thermal protection, which immediately stops the pump if it overheats. The motor is air cooled and equipped with oversized, sealed, greased-for-life ball bearings to ensure silent operation and minimum service.
